To all. whom it "may concern:

Be it known that I, JOHN CALLow, a subject of the King of Great Britain, residing at Liver 001, in the county of Lancaster, in the King om of En land, have invented certain new and useful mprovements in A paratus for Molding Dough, of which the following is a s ecification.

' his invention has for its object an apps-- rat m for molding dough, by imparting to the 4 are a front elevation and cross section of a ortion of the molder, with a device for pushmg the dough pieces from the conveyer into the receptacles of the prover; Fig. 5, a plan view, showing the devices for transferring the den h lumps to the receptacles by tilting them 0 the conveyor; Figs. 6 and 7, a front elevation, showing two arrangements for tiltin the dough lumps off the delivery'device; ig. 8, a plan view; and Fig.9, a front elevation of other devices for transferring the dough lumps to the receptacles of the prover.

A is a drum, which has a series of peripheral grooves a on it, each of which takes a piece of dough and molds it. At the point here the doughis fed into the machine, the es a between the grooves a, are covered 'elded by strips of metal or wood C, which revent the pieces of dough fallin on to the anges a and also lead or direct them into the grooves a. Around a portion of the drum in each groove 0, between the flanges a.

' I place a shield D parallel to the axis of the drum A. The drum A revolvingand the shields D remaining stationary, the dough ieces are molded into compact lumps or ails between their adjacent surfaces, and a very efficient molding effect is produced. The ieces of dough are fed in through a suitable liopper (not shown) in the direction indicatcd at K, and are delivered after being molded into compact lum s, from between the drum Aand shields D t ough a spout at about the oint marked it, on to a conveyor band or other suitable delivery device, pansto War the lumps to a prover or elsewhere.

The drawings show a method of turning" the drum. In those the drum A is mounted so as to revolve on an axle B which is journaled in the frameF. On this shaft is fixed the bevel wheef' ill, which is driven by means of the bevel wheel H and driving shaftJ, to,

which shaft the crank I is secured, driven by an suitable mechanism.

n order to regulate the s ace between the grooves a and the shield I rovide the following mechanism. W is a s aft and W another shaft journaled in hearings in the frame F. On the shaft W is secured a toothed quadrant L. M is a worm journaled in bearings gearing into this quadrant, and N a handle for'turning the worm M. This worm im arts motion to the uadrant L, when the liandle N is turned. n the shaft W is secured a. number of arms P, one for each shield D and bearing against the said shield near one end. These can reject from a sleeve Y secured to the shaft or be each keyed on the shaft W separately. Secured to the other shaft W are similar arms P one for each shield D which bear against the said shields near the other end thereof. S are shoes placed at about midlength of the shield D and mounted on the shaft T. O is a second arm secured to the shaft W, and O a similar arm secured to the shaft W these two arms being cou ledb the connecting rods Q to the shaft whic carries the shoes S. U is a third arm keyed on the shaft and U a similar arm keyed on the shaft W V, a connecting rod cou ling these two arms together. Conse uentl; by turning the toothed quadrant L )y the handle N in one direction, the arms P and I" and simultaneously the shoes S, press against the shields, and force them toward the bottom of the grooves a, while by turning tl uadrant in the reverse direction, the shields expand outward and so increase the s ace between the shields and the bottom 0 the grooves.

In order to prevent the dough from sticking in the drum, the drum grooves a are dusted with floor, the device I use bcin' a brush revolving in the are of a circle, t is brush being mounted upon a reciprocatin Z to which motion-is im arted in any suita le manner. This brush aiternately dips into the flour in the trough Z and then assess over the drum A as far as the feedin evice K.

The mode of action is as allows :--The drum'A being driven at a suitable speed, the

into compact lumps or be 'i0u1'naled in the frame i 5 pact lumps or balls, which are delivered at the point E to conveyor hands by the joint action of the revolving drum A, and the sta tionary shield l). The grooves in the drum are dusted with flour at each revolution by the 10 device alreadydescribed. .ll'largerorsnialler lumps are required all that is iwcessary is to turn the handle N one way or the other and the device will-prod ce the exact size of lumps wanted.

In Figs. 3 and 4 a single shield D is provided having a reciprocating motion imparted to it, parallel to the axis of the drum A. The drum A revolving and the shield l.) reciprocating, the dough'lpieces are molded ls, a very ellicient molding effect being produced. 'Jhe-picces of dough are then delivered one or more at a time, from between the drum A and the shield D down the spout it on to the con- 25 veyer band W or other suitable delivery device. The drawings show by way ot example a method of operating the parts. In these, the drum A isinounted so as to revolve on the axis B see Fig. 4 which is On this shalt i3 is fixed a spur wheel G indicated in dotted lines in Fig. 1 which is driven by means of any suitable pinion. I is a shaft to which an oscillating motion is imparted in any suitable manner, and on this shaft is lixed the driving pinions Q, gearing the racks ll on the Shield 1), so as torecip'rocate the shield as the drum revolves. The dough pieces therefore being fed in between the revolving 4 dl'uin S and the rcciprt'icating shield .l), are

moldedinto; compact lumps otgballs, which are delivered by the lip E on to the conveyor W by the joint action of the shield l) and the drum A. The conveyor Vv' d livers the lumps to a prover or elsewhere and at lixed intervals the pieces of dongh are pushed or tilted oil the conveyor Vv intr the trays of a prover.

In Figs. 3 and 4 the pushing device 7 is 1 hinged at 8 so as to swing thereon, and the dough lumps are pushed fl'OIll the conveyor W into the trays 33 of the prover. The re ciprocation of the pusher is effected by a cam 9 acting on the arm 10 of the pusher 7, the

earn being operated by the shaft carrying the mutilated wheel 2. The conveyor can have either a constant or intermittent or rccipeating motion. In Figs. 3 and 4 it has an intei'inittent movement, this being cll'ected by the mutilated wheels 2 and 3 of known type,

which impart an oscillation to the crank arm 4 having a pawl 5 en aging a ratchet wheel 6. This imparts to t c conveyor a step by ste movement, with an interval of rest,

\? ivhlle the dough lumps are being fed from the drum of the molder or other machine to the receptacles of the prover.

hen the rnolder or other apparatus does not deliver the number of pieces of dough requircd for each row of trays of the prover or other apparatus, then of course some arrangement is needed whereby the inolder shall make more than one delivery of dough lumps in order to lill a complete row of rece .taeles. In the drawings (Figs. 3 and 4) the rum. A is shown delivering four dough lumps X on to the conveyor band W. The conveyor W then moves the four dough. lum )S X forward into the second position X, an the drum A then delivers four more lumps X on to the conveyor band. The pusher 7 now pushes by its swinging or pushing movement the dough lumps X X in to the receptacles of the prover.

In Fig. 5 the dough pieces are tilted oil' the conveyor ban d W into the trays of the rover. For this purpose the pulleys w arount which the eonveyer band W passes are fixed on a frame 12. 13 is an arm pivoted at 14 and operated by means of a cam 15 or any other suitable device. As the can] 15 rotates it rocks the lever about its pivot 1 1 and tilts the pulleys to, and so allows the dough lumps to slide or drop oil the conveyor into the receptacles of the prover. l t is obvious that instead of tilting the pulleys the band could be deflected or tilted by plows or forks to cause the lump to fall into the receptacles or band of the prover. 1

Instead of a conveyor band W any other I suitable delivery device in front of the drum A can he used. Thus in Fig. 6, I show a table 16. This table 16 is mounted on a rack 17 to which is imparted a reciprocating movement by the gear wheels 18. The table 16 is hinged to the rack 17 at 19, so that it will tilt thereon; and so discharge the den 11 lumps into the receptacles of the prover. In place of a rack a right and left handed screw shaft 20 might be used, as shown in Fig. 7, opcratinga nut 21, to which the. table 16 is hinged at 19.

Fig. 8 shows another method of transferplow 22 so arranged that as the table 16 traverses, the dough lumps thereon are by l means of this plow shoved or pushed off.

in Fig. 9 a grab is shown for catching the dough pieces as they traverse along the conveyor band \V. The grab shown in this figure consists of pairs of grab levers or ton s 23 pivoted at 24, with gripping faces 24 w ich l extend. 'the full length of the rows of dough pieces. The pivot is arranged to have a reciprocating movement in the guide 25, the i reciprocation being effected by means of the connecting rod 26 operated by the crank disk 27. 38 is a disk with a cam groove in it, and this groove engages the end of a pivoted spindle which is jointed at 11 to the fixed ring the material to the trays, namely a fixed lever 29 havin a de ending s indle 30 to which is fixed t e col ar 31. 0 this collar is coupled by links 32 the shortarms of the grab levers 23. The crank disk 27 and the cam disk 38 are caused to act in harmony, and as the cam rotates it operates the ab levers 23 so as to ab the 'dough lumps in succession, and t on by the action of the crank disk 27 transfers the lum s to the receptacles 33 of the prover. Itt en releases the lumps and the grabs return to their former osition.
